Abstract：The design processes and methods of eccentric-noncircular gear transmission mechanism were introduced in detail.Based on the geometric model of eccentric-noncircular gear and section-curve closed condition， the design program and the profile of the eccentric-noncircular gear were realized by VB software to conduct 3D modeling，assembly and simulation. The fatigue strength was analyzed on the fracture phenomenon of noncircular gear.Through the stress analysis, the maximum stress of meshing transmission parts in the process of eccentric noncircular gear transplanting mechanism was deduced.To discuss the reason of noncircular gear failure and provide measures to avoid the failure, the material composition of powder-metallurgy gear and the processing technology were analyzed.
